Problem creating graph with gnuplot with time on x-axis
Let me start by saying I'm new to gnuplot and not very good at unix at all..
Anyway, I'm each minute measuring temperature and humidity and saves the last 60 readings along with time in a textfile, values_minute.
The contents of the file is formatted like this: time temperature humidity
I'm trying to create a graph using gnuplot, working with the shell first. Later I will do it with a script that will run once a minute to generate a "realtime" graph to be publish on a web site.
But I'm given the error "invalid command". I'm quite frankly lost.
I'm using my wife's Macbook, and I just noticed that her screen is off axis, but I can't find a way to adjust it. I've tried playing around with resolution in preferences, but nothing.
Maybe a terminal command for adjusting the x and y values of the screen?
Any and all suggestions welcomed :) (2 Replies)
Hi,
I want to generate gnuplot graph from sar data. My problem is the time format.
1- Gnuplot doesn't support the sar format (01:00:59 AM/PM)
2- Sar doesn't provide a switch to choose the format. The only way to do it is by exporting LANG=fr_FR.
Since I have other apps running and... (0 Replies)
Hi,
Im trying to plot a time series with gnuplot. this is my script
set xdata time
set yrange
set timefmt "%H"
set xrange
set format x "%H:%M:%S"
plot "time_vs_times.txt" using 1:2 title 'Interarrival time' with points lw 2
and this is my data

I have a piece of code here that should create a line graph consisting of two lines. It will not render the lines and neither the dates on the x-axis. The y-axis is apparently already scaled for the y-values, so the data interpretation went correctly for at least some of the data.
Does anybody see... (0 Replies)
Hi,
i would like to change color depending from the valuerange.
a gnuplot-script will generate a multiplot and in one graph,
the ranges should have different colors, e.g.
100 ... 133 --> red
200 ... 233 --> blue
300 ... 333 --> orange
400 ... 433 --> green

Hi,
I'm not able to find a solution because I cant find the exact keyword for this.
I wanna make a graph like ive shown in the attachment.
Could someone please share ideas on how to do this.
Thanks! (3 Replies)
For example, I have a file called data.txt. And the content is:
Iker_Casillas 181
Raphael_Varane 182
Sergio_Ramos 182May I know how to write a script for gnuplot, so I can have a bar graph as the column 1 will be the x and column 2 will be the y? And I hope that the x value can be seen clearly.... (0 Replies)

DIGITEMP(1) General Commands Manual DIGITEMP(1)NAME
digitemp - program to read from temperature sensors.
SYNOPSIS
digitemp [options]
DESCRIPTION
DigiTemp uses the Dallas 1-wire bus to read temperatures from digital sensors attached to a serial port adapter. It handles initializing
the bus, searching for attached devices, reading devices and custom log strings. It suports the following temperature devices: DS1820,
DS18S20, DS18B20, DS1822
It also handles the DS2406 1-wire hub switches, and DS2422 and DS2423 counters.
DigiTemp uses either the DS9097 passive serial port adapter, or the DS2480B based DS9097U adapter (recommended).
OPTIONS
At least 1 action must be given, along with some optional arguments. Actions are one (and only on) of the -w -t -a -w options
-h, -? Show summary of options.
-v Show verbose output.
-i Initialize .digitemprc file, search the bus for all supported devices.
-w Walk the full device tree and display the serial number and type of all devices detected on the bus.
-s /dev/ttyS0
Set serial port to use. Make sure you have permission to access this port.
-l /var/log/temperature
Send output to logfile, the output format is defined by the .B -o command
-c digitemp.conf
Set digitemp configuration file. The default is .digitemprc in the current directory.
-r 1000
Read delay in ms. This sets the amount of time to wait between sending the temperature conversion command and reading the result.
The DS18S20 takes about 750mS to do the temperature conversion. Default is 1000mS (1 sec).
-t # Read sensor number #, the # depends on the order of the sensors in the .digitemprc file.
-q Quiet output, no copyright banner.
-a Read all sensors.
-A Treat DS2438 as A/D converter, output raw voltages
-d 5 Delay between samples (in seconds).
-n 50 Number of times to repeat the command.
-O"counter format string"
See Counter Format below.
-o [1..3] ["output format string"]
See Temperature Format below.
-H"Humidity format string"
See Humidity Format below.
Temperature Format
The temperature format can be either a numeric value, or a string. The numeric values select pre-configured output formats:
1 = One line per sensor, time, C, F (default)
2 = One line per sample, elapsed time, temperature in C
3 = Same as #2, except temperature is in F
#2 and #3 have the data separated by tabs, suitable for import into a spreadsheet or other graphing software.
The format string uses strftime tokens plus 5 special ones for DigiTemp:
%s for sensor #
%C for centigrade
%F for fahrenheit
%R to output the hex serial number
%N for seconds since Epoch.
The case of the token is important! The default format string is: "%b %d %H:%M:%S Sensor %s C: %.2C F: %.2F" which gives you an output of:
May 24 21:25:43 Sensor 0 C: 23.66 F: 74.59
The DS2438 sensor can be used for a variety of things. It includes a temperature sensor and A/D converter. DigiTemp defaults to using it as
a humidity sensor. The raw voltages can be displayed by passing the -A argument
When the -o2 or -o3 log options are used the attached DS2438's temperatures will be output without the humidity.
Counter Format String
The counter format string is similar, adding these tokens:
%n is the counter #, which depends on its position in the .digitemprc file
%C is the count in decimal.
Humidity Format String
The Humidity format string is the same as the temperature format string with the addition of this format specifier:
%h is the humidity in 0-100%
